US Patent 11949891 Systems and methods for region-of-interest tone remapping

Systems and methods are described for providing viewers of streamed video content with the option to view alternative video content in which alternative tone maps are applied to respective regions of interest. In some embodiments, the streamed video content is divided into slices, and alternative tone maps are applied to respective regions of interest within the slices. When a server receives a request from a client for alternative tone mappings of different regions, slices with the appropriate mapping may be assembled on demand and delivered to the client in a single video stream. Tone mappings may be used, for example, to highlight particular objects, such as players in a sporting event captured in the streamed video content.
